KING OA8300 Jack Replacement Head HDTV Directional Over-the-Air Antenna - White

Awesome reception!!!! Installed in 5 minutes.

Great product we get more Chanel’s than the original antenna easy install

Works great. Picture quality is very good. Was missing the power supply and amazon adjusted the price. Great service.

Update 11-9. Customer service contacted me and apologized for lack of service. Immediately sent a new antenna, I am very pleased with their response. So for now improved to 5 stars, I will update again if I experience same problem. But will give customer service a chance to rectify.Original post Oct 18. I really like the sleek design, the less weight, and the improved channel performance of the King Jack replacement head antenna. But I believe that the units head assembly screws were not adequate for an outdoor environment. So since I purchased them in June 2018 and the product has a 1 year warranty I called King customer service to stand behind the warranty.Customer service agent "Ricky" told me that they would not warranty that problem since it didn't effect performance. I asked do you have these types of complaints in the past maybe they received a bad batch of hardware? A simple return of the unit and replacement of the hardware would have satisfied me. I also suggested just sending me the hardware and I could do it. He told me we are just going to send you the same hardware it will happen again. Ugh "faceplant".So I guess make your own mind up but I have rust marks on my roof from this antenna. I probably will figure a way to clean and coat the hardware. Since this was a very simple problem that King had no interest in supporting I really would not recommend to my friends and fellow RVers. I have purchased more expensive King products and haven't had to use the warranty yet. Not looking forward to any of those conversations if they were to arise.

I ordered the King Jack replacement for our RV as the ‘batwing’ was flapping a bit when on the road and leaving wear marks on the rubber roof. In addition we were receiving numerous pixelated channels. The King Jack installed quickly and simply. Our reception went from 66 channels from the batwing with 20 of those too pixelated to watch, to 75 channels with zero pixelated using the King Jack. Note; the batwing had three rubber feet on the bottom. Once the King was installed the aluminum antenna mounting arms now laid directly on the roof. I addressed this by removing two of the batwing rubber feet, drilling two 0.332” holes in the bottom of the lower mounting arm near the top and inserting the two rubber feet as a cushion between the aluminum arm and the rubber roof. I also discovered the assembly screws used on the King were ferrous and might eventually leave rust stains on the white roof so after I was sure it worked, I replaced the nine of them with #4 3/8” stainless and #8 1/2” stainless for the four screws used to attach the mounting bracket to the King.I used my existing power pack from the batwing to power the King. Thus making the replacement even easier. Since proper operation requires the antenna to be raised, I continue to use my clothes pin method to remind me to lower it before breaking camp. I keep a labeled clothes pin on the antenna crank and move it to the gear shifter whenever I raise the antenna.

I routinely camp out in the middle of nowhere with my 2010 travel trailer. I'm at least 40 miles from the nearest TV station transmission, and using the stock "bat-wing" antenna that came with my unit, I was only able to receive at most 1 digital channel, and even then only if conditions were perfect.This King OA8300 was a breeze to install. For my Trailer, all I had to do was remove two pins that were held on with E-Clips, slide off the old antenna, and install the new antenna. There are even replacement clips in the box if you happen to lose one in the process.It does come with an amplifier that you can use, but my trailer has one built into the connections, so I opted to keep using that one, and stowed the one that came with the new antenna in case there is a problem in the future.Once I hooked it up and ran the auto-channel scan, I was floored when it came up with 40 channels! About 1/3 of the ones it discovered needed to have the antenna turned to bring them in clearly, but it did a great job at detecting them, and of the 40, I couldn't find any of them that were unwatchable as long as I turned the antenna to maximize the signal.This antenna should be stock on all new Travel Trailers!

We camp a lot in state parks where there is no cable TV. My hubby has to be able get a few channels so we purchased this and so far we have been very pleased. It was extremely easy to install.

The King Jack(KJ), is packaged very nicely and all parts were present. I installed it as a replacement to a RV Batwing(BW), only because the times we camped where cable connection was not available we usually were wishing for more channel coverage (Saturday college Football games). Installation in my case was a snap, simply remove the pins on the BW & aluminum arms, disconnect coax, pull BW off, place KJ with bracket install onto aluminum arms, reinstall pins and coax. Like most I ran a channel scan before and after; the score BW-47, KJ-42. However I went deeper then that I looked at each channel prior because on my TV, it will show a channel is there but with nothing but a message that states Low Signal. I had 5 weak signals with the BW, all were subchannels of the same channel X.x . Using the website NoCable.org for my zip code, I noticed that they were the only VHF channels in my area and also 55miles away. With the KJ it did not even find these channels at all. So I believe that the KJ probably has a higher gain in the UHF band then the BW and the BW beats the KJ in the VHF range. This is the reason that Winegard added the smaller radials (AKA Wingman) to the BW. I can't go with that option due to mount location. That is why I only gave the KJ a 3 star. Too many variables, broad frequency range, transmission range from you the receiver, and mount location, makes it tuff to please all, in all locations.
